Web23 feb. 2024 · Chitin hydrolysis involves glycoside hydrolase family 18 (GH18) chitinases. In insects, chitin hydrolysis is essential for periodic shedding of the old cuticle ecdysis and proceeds via a pathway different from that in the well studied bacterial chitinolytic system. Webbiomimetics [20,21], as commercial products. Numerous studies have been conducted to extract or optimize the extraction conditions of chitin from a variety of sources [3–6,22,23], but only few solvents can be used for dissolving or dispersing chitin for further processing [24]. However, when the size of chitin is reduced to nanoscale, it readily
